you'll need to know that it's not just about the price. It's also about the way the puppy is handled, raised and socialized, and it's about the environment in which it's raised. The following are some of the key factors to consider when you're deciding whether to buy a puppy online. Appearance and Personality You'll want to look for a puppy that's a good size for its age. Puppies under 2 months are often too young to be safely left alone, and too small to be properly socialized. They're also more likely to be aggressive, and have trouble getting along with other dogs. Also, look for a puppy that's happy, healthy and well-socialized. A puppy that's scared, or doesn't have a lot of energy is more likely to be aggressive. Look for a puppy that's friendly and well-behaved, and who has lots of play time. Puppies who are not as interested in playing as their older siblings, or who are overly active, are also more likely to be aggressive. Breed Puppies that are purebred, or a mix of purebred and other breeds, are more likely to be socialized and have fewer behavioral problems. They're also more likely to be healthy and have a good quality of life. However, if you're looking for a purebred puppy, it's important to be aware that some of the more popular breeds, such as poodles, golden retrievers and German shepherds, are considered "designer" breeds. These are popular because of their looks, and because they're bred for certain traits. They may be very well-behaved, but they can also be prone to certain health problems. If you're looking for a puppy that's a mix of a designer breed and a purebred, look for a puppy that's between 2 and 4 months old. They're usually a little more active, and have more energy, but they're also less likely to have health problems.
